The former world No. 1 won the first set comfortably against anerror-prone Djokovic in 25 minutes, but faded badly in the second as he made a total of 47 unforced errors.

The Swiss won just 57 percent of first serve points in the second and it got worse in the third as Djokovic broke at the first attempt.

"I thought I was playing okay in the first set but it was always going to be tough in the wind," said Federer, "I already felt it in the warm up. It was coming across the court. I struggled heavily. It was tough."
